Pumped or electrically heated? Either way, I would advise your friend to stay well away from the electrics and call in a professional, they probably don't know what they're doing. End result will likely be an electrically heated shower wired into a 32A ring or a lighting circuit

Yup! Unless, of course, someone has wired an extractor fan to an ex DP shower isolator, but let's not even get into the logistics of a 40-45A breaker feeding an extractor fan
I've seen an old shower circuit switching the light in a small cloakroom. The bathroom had been converted into a bedroom and where the shower used to be a door had been knocked through to the landing so there was a toilet upstairs, easiest solution was to re-use the ex shower circuit for the light 
its amazing how you can terminate a 6mm t&e into a lamp holder when you have to 
and thats not the best part, the pull cord was in the bedroom half, no problem though, the guy had just drilled a hole in the wall and fed the pullcord through 
Anyway it was all removed when my friend bought the house and i re-wired it properly from the upstairs lighting circuit. The house had several other disaster DIY electrics but not really worth mentioning.
All the best

Most liklely outcome is that the breaker in the consumer unit will trip shortly after the shower is turned on, how quickly depends on the size of the shower and by how much the circuit is overloaded.
If the fuseboard is an old rewirable type then its possible the fuse might hold in, starting either a fire in the CU as the fuse heats up or causing some other weak point in the circuit to overheat.
